3 Claims. (Cl. 10S-409) This invention relates to railway car side wallsand is primarily concerned with a novel means and method of securing arailway car side wall to the underframe of the car.

The principal object of the invention is to provide in a railway car amember depending from the side wall and a side sill attached to theunderframe, the member and the side sill being adapted to be securedtogether to form a beam.

A more specific object of the invention is to provide in a railway caran L-shaped member depending from the side wall and L-shaped side sillattached to the underframe, the member `and the side sill being adaptedto be secured together to form a rectangular-shaped beam.

Another object of the invention is to provide in a railway car a methodof securing a side wall to an underframe which includes the steps ofsecuring a member to the side wall and securing a side sill to theunderfrarne and securing the member to the side sill. j

Another object of the invention is to provide in a railway car a methodof securing a side wall to an underframe which includes the steps ofsecuring a member to the side wall to form one subassembly and securinga side sill to the underframe to form .another subassembly and securingthe first subassembly to the second subassembly by securing the memberto the side sill.

An important object of the invention is to provide in a railway car aside sill and a side sill reinforcement depending from the side sill andsecured thereto and a cross member Seated upon the side sillreinforcement and secured thereto and flooring positioned upon the crossmember and secured to the side sill.

Another object of the invention is to provide in a railway car anL-shaped side sill and an L-shaped side sill reinforcement having oneflange depending from the side sill and secured thereto and one ilangeof the side sill and the other flange of the side sill reinforcementprojecting in opposite directions and across member seated upon theother flange of the side sill reinforcement and secured thereto andllooring positioned upon the cross member and secured to the otherflange on the side sill.

The foregoing and other objects of the invention are attained by theyconstruction and arrangement illustrated in the accompanying drawingswherein:

Fig. 1 is a fragmentary side elevational View of a railway box carshowing a portion of the side wall and showing a portion of theunderframe;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1; and

Fig. 4 is :a cross sectional view through the bolster taken on the line4-4 of Fig. 1.

The invention proposes a novel means and method of securing the sidewall of a railway car to the underframe thereof. A member is dependinglysecured to the bottom of the side Wall, the member and the side walltogether forming one subassembly. An outturned side sill is at-StatestPate'nt O ICC tached to the underframe, the side sill andtheunderframe together forming another subassembly. The `lirst subassemblyis secured to the second subassembly by securing the member to the sidesill. The member and the side sill when secured together form a beam ofrectangular cross section. means of securing the side sill, side sillreinforcement, cross member, and flooring together. The side sillreinforcement is dependingly secured to the side sill, and the crossmember is seated upon the ilange of the side sill reinforcement and issecured thereto. The flooring is positioned upon the cross member and issecured to one flange of the side sill. t f A In the drawings, 10generally designates a railway house car or railway box car having anunderframe 11 and side walls 12. The underframe 11 comprises a centersill 13 and a cross member or bolster 14. The cross member or bolster 14is made up of a web plate 15, a bottom cover plate 16, and a top coverplate 17. The sidewall 12 is comprised of a metal side sheathing 18Ihaving vertically extending corrugations 19 therein and fui-ring strips20 are disposed in the vertically extending corrugations. Bolts 21 aredisposed in the corrugations 19 and welded thereto and extend throughthe furring strips 20 and nuts 22 are threaded on the bolts and serve tohold the fur-ring strips in place in the corrugations.

An L-s'haped member 23 extends the entire length of the car and issecured to the bottom of the side wall 12 and depends therefrom. Themember 23 has a vertical flange and a horizontal ilange integral withthe vertical flange and the horizontal flange projects toward theinside` of the car. An L-shaped side sill 24` extends the entire lengthof the car and is secured to the member 23 by welds 25 and 26. The sidesill 24 has a vertical flange and a horizontal flange integral with thevertical flange and the horizontal ilange projects away from the car. AnL-shaped side sill reinforcement 27 extends between and beyond the carholsters and has one llange 28 depending from the side sill 24 andsecured thereto by a Weld' 29. One llange 30 of the side sill 24 and theother ilange 31 of the side sill reinforcement 27 project in oppositedirections as best shown in Figs. 3 and 4. The cross member 14 is seatedupon the flange 31 of the side sill reinforcement and the flange 31 issecured to the cross member by a weld 32 and the flange 28 of thereinforcement is secured to the cross mmeber by a weld 33. A iloor 34 iscomprised of a plurality 'of metal sheets 35 arranged end to end andhaving corrugations 36 extending transversely of the car and woodenboards 37 are disposed in the corrugations; this being the iloorconstruction over the major length of the car. However, over thebolsters 14 this floor construction is changed somewhat. The endmastcorrugation 38 of the adjacent sheet 35 is positioned upon and welded tothe top cover plate 17 of the bolster 14 as best shown in Fig. l. Asingle metal member 39 in the form lof a corrugation extendstransversely of the car over the middle of the bolster 14 and is weldedto the top cover plate 17 of the bolster. A pair of wooden boards 40 and41 are positioned upon the top cover plate 17 on opposite sides of themember 39.

The sheets 35 are welded to the other llange 42 of the side sill 24 by aweld 43 as shown in Fig. 3, and the member 39 is positioned upon thecross member 14 and welded to the flange 42 of the side sill 24 by aweld 44 as shown in Fig. 4. Spaced gusset plates 45 are secured to theside sill 24 by welds 46 and to the side sill reinforcement 27 by welds47. The member 23 Iand the side sill 24 together form a hollow beamrectangular-shaped in crosssection and the llanges 30, 42, 48, and 49form the four sides of the beam, as best shown in Figs. 3 and 4.

The method of securing the side wall 12 to the underframe 11 comprisesthe following steps. The inturned Patented Aug. 2,7, 1957` Theinventionfurther proposes a novel` Y A 3 Y L-shaped member 23 is welded to thebottom of the side wall 12 to form one subassembly. The outturned L-shaped side sill 24 is welded to the underframe l1 to form Ianothersubassembly. The first subassembly is then secured to the secondsubassembly by welding the member 23 to the side sill 24 by welds 25 and26 as best shown in Figs. 3 and 4.

From the foregoing it will be seen that there has been provided a novelmeans and method of attaching the side wall of a railway car to theunderframe thereof so that a beam extending the entire length of the caris formed at the point of joinder of the side wall to the underframewhich greatly strengthens the car body. Further, there has been provideda novel means of securing the side sill,

side sill reinforcement, cross member, and ooring to# gether whichgreatly strengthens the car body.
